  1. your post is very difficult to read since you didn’t quote your input correctly. see Please Read This First: Guidelines and Suggestions for posting LAMMPS questions
  2. since you are using a “meta” package to create your LAMMPS simulation input, your best changes for on-topic advice is probably to contact the author of that package or post in a suitable forum for that software.
